9 Claims.

This invention relates to improvements in hinges, and refersparticularly to concealed hinges.

It is an object of the invention to provide a simple, strong, anddurable form of hinge wherein the movable plate, which is intended forattachment to a door, is swung outwardly and forwardly from thestationary plate, which is intended to be mounted upon a doorpost orframe,

l0 when the hinge is opened so that the movable plate then restsmaterially in advance of the stationary plate; and wherein'all theportions of the hinge are concealed, partly between the two plates andpartly behind one of them, when the hinge is closed.

Another object of the invention is to provide a hinge consisting of twoplates intended for attachment to a door and doorpost or framerespectively, one of the plates being apertured for the passage of atongue extending from the other plate, and guide means for the tonguewhich project both forwardly and rearwardly from the apertured plate,sothat the tongue passes through the aperture as the hinge is opened orclosed and g5 is guided throughout its movement.

A further object of the invention is to provide a hinge wherein a stopis provided to limit the angular movement of the two plates to oneanother.

Having thus briefly stated some of the objects and advantages of theinvention, we will now proceed to describe a preferred embodimentthereof with the, aid of the accompanying drawings, in which:

Figure 1 illustrates a plan view of the hinge when closed,

Figure 2 is a side 'view thereof.

Figure 3 shows a plan view of the hinge when fully open, and

Figure 4 is a side view thereof.

Figures 5 and 6 are views on the lines 5-5 and 6-6 respectively ofFigure 3.

Figure '7 is a plan view of the hinge when partially open.

Referring to the drawings, I and 2 designate two vertical plates eitherone of which is intended for attachment to a doorpost or frame and theother to a door. Both the plates l and 2 are provided in the presentinstance with a plurality 50 of openings 3 for the passage of screws-notshownto secure these plates to the parts to be connected by the hinge.

The plate I is apertured at 4, usually substantially centrally of itsheight and preferably from 55 one of its vertical margins and for thegreater portion of its width. Extending both forwardly and rearwardlyfrom the plate I are horizontal guides 5, the adjacent faces of whichare flush with the upper and lower sides of the aperture 4. Formedthrough the guides 5 are vertically aligned slots 6 which extend acrossand on both sides of the plate I, and integral with the latter adjacentits vertical margin through which the aperture 4 does not extend are aplurality of spaced and vertically aligned knuckles l. The latter arepositioned forwardly relative to the plate I, and one of the saidknuckles is located in the same horizontal plane as at least a portionof the aperture 4.

Extending through the knuckle 1 is a pin 8 on which one extremity ofeach of two links 9 are pivotally mounted. These links are arranged oneabove the other on opposite sides of the central knuckle 1. Formedintegral with the plate 2 are other vertically spaced knuckles Hi,which,

when the hinge is closed, extend towards the plate l and towards theside thereof remote from the knuckles l. A second pin l l passes'boththrough the knuckles l0 and the opposite extremities of the links 9.

A tongue l2, which projects horizontally from the plate 2 and isslidable between the guides 5, has a guide pin l3 extending verticallythrough its outer extremity which travels in the slots 6. In order toinsure clearance for the extremities of the guide pin I3 recesses 14 maybe formed through those portions of the plate I contiguous to the outersides of the slots 6. The tongue [2, which is preferably so formed'at Inas to contact the central knuckle I when the hinge is fully open andthus form a stop, may either be integral with the plate 2, or securedthereto as by a screw l5 shown in Figures 3 and 5.

As the hinge is opened, assuming that theplate l remains stationary, therear portions 6a. of the slots 6 cause the plate 2 to turn suflicientlyfor a door--not shownsecured to the said plate 2 to swing clear of thedoor frame. The inclination of the plates I and 2 to oneanother when thehinge is thus partly open may be clearly seen from Figure 7. As thehinge continues ti)v open the guide pin l3 travels towards the frontextremities of the slots 6 along a more nearly straight path. Duringthis portion of the move-: ment the plate 2 swings forwardly relative tothe the knuckles l and ID on opposite sides of the plates I and 2 and bymaking the links substantially S-shaped as shown, that when the hinge isclosed the two said plates rest parallel, and in close proximity, to oneanother. The rear portions of the guides 5 may also be strengthened by avertical connecting wall 5a.

' While in the foregoing thepreferred construction of the hinge has beendescribed and shown, it is understood that alterations and modificationsmay be made thereto so long as they fall within the scope of theappended claims.

What we claim is:

1. A hinge consisting of two flat plates which, when the hinge isclosed, rest in proximity and substantially parallel to one another,connecting means extending substantially diagonally between the twoplates when the hinge is closed, said connecting means being pivoted ateach extremity to one of the plates, the two pivot axes being parallel,a tongue integral with one plate projecting laterally therefrom, guidemeans integral with the other plate and extending laterally therefrom,and cooperating means carried by the tongue and guide means forcontrolling the path of movement of one plate relative to the other.

2. A hinge consisting of two flat plates one of which is apertured, atongue integral with and eX- tending laterally from the other plate andbeing slidable through said aperture, guide means integral with andextending laterally from the apertured plate, means carried by the outerextremity of the tongue slidable in the guide means, and connectingmeans pivoted at each extremity to one of the plates and positionedbetween the adjacent faces of the plate when the hinge is closed. 1 3. Ahinge consisting of two plates one of which is apertured, a tongueextending from the other plate'and being slidable through said aperture,guide means extending laterally from both sides of the apertured plateand through the aperture, means carried by the outer extremity of thetongue slidable in the guide means, and connecting means for the platespivoted at each extremity to one of the latter about parallel axes.

4. A hinge consisting of two fiat plates one of which is apertured, atongue integral with and extending laterally from the other plateslidable through said aperture, guide means for the outer extremity ofthe tongue integral with and extending laterally from the aperturedplate, and connecting means pivoted at each extremity to one of theplates and positioned between the plates when the hinge is closed, saidtongue being so formed that a portion thereof contacts a portion of theapertured plate to limit the opening of the hinge.

5. A hinge consisting of two plates which lie substantially parallel andin proximity to one another when the hinge is closed, a tongue integralwith and extending laterally from one plate, guide means integral withand extending laterally from the other plate, a projection extendingfrom the tongue slidable in the guide means, said tongue being so formedthat a portion thereof contacts a portion of the other plate to limitthe maximum angularity of the plates to one another, and connectingmeans between the plates pivoted at each extremity to one of the latter,said connecting means being substantially diagonally disposed betweenthe plates when the hinge is closed.

6. A hinge consisting of two plates which lie substantially parallel andin proximity to one another when the hinge is closed, one of the platesbeing apertured, a tongue extending from the other plate and beingslidable through the aperture, slotted guides extending laterally fromboth sides of the apertured plate and through the aperture, a projectioncarried by the outer extremity of the tongue slidable in the slots andthrough the aperture, and connecting means pivoted at each extremity toone of the plates and extending substantially diagonally between thelatter when the hinge is closed.

'7. A hinge comprising two plates which are substantially parallel andin proximity to one another when the hinge is closed, spaced knucklesintegral with each plate, the two sets of knuckles tend across and onboth sides of the apertured plate, a projection extending from the outerextremity of the tongue slidable in the slots, and the latter being soformed that as the plates move apart the other plate is moved forwardlyfrom the apertured plate as the inclination of the two plates to oneanother increases.

8. A hinge comprising two plates which are substantially parallel acrosstheir faces and in proximity to one another when the hinge is closed,spaced knuckles integral with each plate, the two sets of knuckles beingpositioned adjacent diagonally opposite margins of the plates when thehinge is closed, links pivoted at each extremity to one set of knucklesand disposed between the plates, a tongue projecting from one of theplates, and guide means for the outer extremity of the tongue to controlthe path of movement of the first named plate, said guide meansextending across and on both sides of the other plate, and supported bythe latter.

9. A hinge comprising two plates which are substantially parallel acrosstheir faces and in proximity to one anotherwhen the hinge is closed,spaced knuckles integral witheach plate, the two sets of knuckles beingpositioned adjacent diagonally opposite margins of the plates when thehinge is closed, links pivoted at each extremity to one set of knucklesand disposed between the plates, one of the plates being apertured, atongue extending from the other plate and through the aperture, guidesextending from the: apertured plate to receive the outer extremity ofthe tongue and control the path of movement of the other plate, aportion at least of the tongue being in alignment with one of the eyeson the first named plate, and said tongue being so formed that a portionthereof contacts the knuckle in alignment with it to limit the maximuminclination of the plates to one another.
